Check Digit Verification of cas no

The CAS Registry Mumber 872513-62-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,5,1 and 3 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 872513-62:
(8*8)+(7*7)+(6*2)+(5*5)+(4*1)+(3*3)+(2*6)+(1*2)=177
177 % 10 = 7
So 872513-62-7 is a valid CAS Registry Number.

Iridium and phosphine promoted C-F bond activation: The C-S cross-coupling of aryl fluorides with diaryl disulfides to synthesize thioethers

Li, Liang,Miao, Hongyan,Ding, Yuqiang

, p. 6405 - 6408 (2015)

Carbon-fluorine bond is the strongest known single bond to carbon and proved very difficult to cleave. An iridium and phosphine promoted C-F bond activation was developed, for the first time achieving the C-S cross-coupling reaction of disulfides with aryl fluorides using iridium complex. The corresponding monoarylthiolation products were obtained at moderate to good yields. Thus, it represents a new method for the synthesis of aryl sulfides through C-F bond activation.
